[0025] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This utility model proposes a clamp airtightness testing device, such as Figures 1 to 3 As shown, a preferred embodiment of the clamp airtightness testing device of this utility model includes: a frame, a water tank 10, an air circuit assembly 20, a test module 30 and a CCD assembly 40 disposed on the frame.
[0028] The output end of the air path component 20 is connected to the clamp to be tested 50. The test module 30 is used to clamp the clamp to be tested 50 and to put or take out the clamp to be tested into the water tank 10. The CCD component 40 is set on the outside of the water tank 10 facing the clamp to be tested 50. The CCD component 40 is used to photograph the state of the bubbles inside the water tank 10.
[0029] This embodiment uses the CCD component 40 to capture the state of air bubbles in the water tank 10, visually analyzes the presence or absence of air bubbles, and then determines whether the clamp 50 under test has a leakage defect. This can reduce the intensity of manual labor and improve the efficiency and accuracy of clamp airtightness testing.
[0030] In this embodiment, the water in the water tank 10 is circulating water, not ordinary water. Circulating water itself does not produce bubbles. Experimental tests show that circulating water can remove bubbles adhering to the surface of the pipe sleeve, but cannot remove bubbles inside the clamp 50 under test. When ordinary water is used in the water tank 10, bubbles will form on the surface of the clamp when it is first placed in the tank. This can lead to false positives if the clamp 50 under test does not have any leakage defects.
[0031] Therefore, by adding circulating water instead of ordinary water to the water tank 10, this utility model can avoid false detection when the clamp 50 under test does not have any air leakage defects, thereby improving the detection accuracy and efficiency.
[0032] Furthermore, in this embodiment, the water tank 10 is made of corrosion-resistant stainless steel.
[0033] In this embodiment, fresh water can be injected and wastewater discharged by manually operating the valve of the water tank 10, or the equipment can automatically inject or drain water. A water supply system needs to be configured in the layout of the testing workshop. Water inlet connectors and wastewater discharge channels need to be installed at the corresponding locations of the equipment. The connector types need to be clearly defined. The water supply system needs to be equipped with a water purification and sterilization device to ensure that the water quality meets the standards.
[0034] like Figure 2 As shown, in this embodiment, the air circuit assembly 20 includes an air pipe 201, a first ball valve 202, a filter 203, a manual pressure regulating valve 204, a first high-pressure resistant solenoid valve 205, and a pressure regulating device 206 sequentially disposed on the air pipe 201. The output end of the pressure regulating device 206 is connected to the clamp 50 to be tested.
[0035] The pneumatic circuit assembly 20 also includes a mechanical gauge 207 and a second ball valve 208 disposed on the pneumatic circuit.
[0036] The gas path assembly 20 also includes a second high-pressure resistant solenoid valve 209 and a high-pressure resistant silencer 210 disposed on the gas path.
[0037] like Figure 3 As shown, the test module 30 includes a Z-axis fixing block 301 mounted on the frame, a first drive motor 302 and a driven wheel mounted on the Z-axis fixing block 301, a drive wheel connected to the first drive motor 302, and an L-shaped air passage pipe 303 connected to the pressure regulating device 206. The drive wheel and the driven wheel are connected by a synchronous belt 304. The top of the air passage pipe 303 is connected to the output end of the pressure regulating device 206 and is connected to the synchronous belt 304 by a clamping block 305. The clamp to be tested 50 is mounted at the bottom of the air passage pipe 303.
[0038] The test module 30 also includes a rotary joint 306 and a second drive motor 307 for driving the rotary joint 306 to rotate so as to drive the clamp 50 under test to rotate. One end of the rotary joint 306 is connected to the air pipeline 303, and the other end is connected to the clamp 50 under test.
[0039] During testing, the clamp 50 to be tested is first pressurized and placed in the water tank 10. Then, the second drive motor 307 is started to drive the rotary joint 306 to rotate, thereby rotating the clamp 50 to be tested and flushing away air bubbles on the surface of the clamp 50. Then, the second drive motor 307 is turned off, and the clamp 50 to be tested is pressurized for a preset time. The state of the air bubbles in the water tank 10 is then captured by the CCD component 40. The presence or absence of air bubbles is visually analyzed to determine whether the clamp 50 to be tested has a leakage defect, which can further improve the accuracy and efficiency of clamp airtightness testing.
[0040] In summary, the beneficial effects of this utility model clamp airtightness testing device are:
[0041] This utility model, through the above technical solution, includes: a frame, a water tank, an air circuit assembly, a test module, and a CCD assembly mounted on the frame; the output end of the air circuit assembly is connected to the clamp to be tested, the test module is used to clamp the clamp to be tested, and to place or remove the clamp to be tested into the water tank; the CCD assembly is positioned on the outside of the water tank facing the clamp to be tested, and is used to photograph the state of air bubbles inside the water tank, which can effectively improve the accuracy and efficiency of clamp airtightness testing.
